WebFollow the given steps to construct a 90-degree angle using a compass. Step 1: Draw a ray AB with help of a ruler. Step 2: Put the tip of the compass at A and draw an arc that cuts ray AB and mark that cut point as C. Step 3: Put the compass tip at C and draw an arc of radius AC that cuts the arc drawn in step 2 and mark that cut point as D. Web2 dagen geleden · Then I asked for the angle between B and C. It answered 34 degrees, because the angles of a triangle must add to 180 degrees. Then I asked how this could be a right triangle if none of the angles was 90 degrees. I asked how the angle between A and C could be 101 degrees when it looks so much smaller than the other angles.
